A further object of my invention is to provide. a compact advantageous combination of fire pots and a broiling grate.

A further object of my invention is to secure an advantageous distribution of heat without interference with or from the broilconstruction, all as will be hereinafter fully set forth.

Figure 1 represents a perspective view of my range, a portion of the top front frame of which is broken away. Fig. 2 represents a partial vertical section of Fig. 1 upon line ad-w thereof. Fig. 3 represents a vertical section of Fig. 1 upon line yy thereof. Fig. 4 represents a perspective view of my water back having a portion of the frame thereof broken away. Fig. 5 represents in elevation a front portion of my range with the top removed.

. Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings ':1 designates the frame of my range which is made up of lower front plates 2 and divided side plates consisting of parts 3, 4 and 5, also back plates 6, top plate 7 and an upper front face 8. The junction between theside plates. 3 and 4 is formed preferably by strips 9 integral with one of these plates and attached by the bolts 10 to the other thereof. It will be seen that there are side'plates 3, 4 and 5 preferably so connected at each side of the range. The. upper plate 5 at each side, rests upon the corresponding plate 4 and is ordinarily held thereon by the mere weight of the structure, but may be attached in the same manner as indicated in regard'to plates 3 and 4 or otherwise, as desirable.

The horizontal front or top of the range is formed by a top 11 having openings therein containing removable lids 12, 13 and 14 and the annular ring 15. This last is removable also and forms a support for the lid 14 in the well known manner. The lids permit access to the parts shown in Fig. 1 where the top of the range is shown broken away.

Within the frame and between the side plates 5, back plate 6 and face 8 I form a baking oven 16 spaced from the walls of the frame to allow vertical front and back passages or openings 17 and 18. Above the baking oven 16 the space bet-ween the top of the baking oven and the plate 7 provides a passage 19 into which open apertures 20 in the plates 5, which are provided for cleanin purposes. An aperture 21 in the plate 7 1s provided for the same purpose. I also provide apertures 22 in the side plates of the range for cleaning purposes. The oven 16 is available from either side of my range by means of doors 23 and 24 opening thereinto. These are illustrated as closing openings made in the plates 5 and may be placed in one such plate only if desired. Below the oven 16 I have provided a hot closet 25 for dishes, etc. available by doors 26 and 27 and for much the same purpose I provide a shelf 28. I strengthen the face 8 by means of ribs 29.

In the plate 3 of the side of my range I indicate the draft openings 30 opening into the ash pit and which openings may be closed in any suitable manner.

In the front of my range I place doors 31 and 32 which are preferably vertically movable within suitable guides by means of handles 33 and 34 to permit access to fire pots having grates 35 and 36 upon which the main range fires are intended to be placed. Below the doors 31 and 32 I place preferably vertically movable doors 37 and 38 provided with handles 39 and 40, by means of which access is had to the ash pits 41 and 42. These ash pits have rear openings 43 and 44 in the back plate 6. The doors 37 and 38 also provide for other draft for the fire pots having grates 35 and 36.

Between the fire pots and in the front part of the range I provide grate 45, which This structure is best seen in Fig. 3. The

plates 56 and 60 are provided with flanged 45 in the lower part thereof, supporting the upper edge 64 of this grate and above this oven 52, having a removable bottom 53,

which when removed permits access to the broiling grate and fire thereon through this door 51. boundaries 55 and 56 of this oven 52 cooperate with other frame parts of the range to produce passages or spaces 58, 57 and 59 respectively; by which gases from the main, fires of the range are permitted access toand can surround the oven 52. The lower limiting surface of the space or passage 59 is the plate60. Openings6l permit free passage of gas from the space 58 into the space 59.

recesses 62 and 63. \Vithin the recess 62 the removable oven bottom 53 is placed while the recess 63 holds the removable grate edge 64 seats a lid or plate 65. The space 59 below the oven and also the space 58 at the back of the oven are in communication with p the broiling grate when the plate 65 is removed and a passage is thus provided for gases fromthe broiling grate, and from the lower openings 66 at each side by which the space beneath the intermediate oven 52 is conneeted'with the spaces 67 and 68, lying between the side walls of the intermediate oven and the-fire pots upon either side. It will be noted that when the plate 53 is in placethis space 59 beneath the oven is not directly in communication with the interior 7 of the oven, but thatiwhen it is removed the interior of'the oven is in direct communication with the space. The inner walls 67 and 68 of the passages or spaces .67 and 68 constitute the side walls of the intermediate oven and reach back to the rear wall 58 of the space 58. Refractory material 69 is used to protect the metal parts of the fire pots from injury by the fire therein.

On the upper side of the top 55 of the intermediate oven, as best shown in Fig. 1, and between this top and the top 11 of the range I place guard strips 70 which project from the rear of the front portion of my range a considerable part of the distance to the front thereof. These perform a double function. They support the top of the range and prevent gases from the main fire pots from passing through the aperture 71, under certain circumstances hereinafter described, without previously heating the oven 52. A damper'70" is used for the purpose of closing the space'between the ends of the strips The back 54 and upper and lower the boiler 81 in case of requirement of re plates are removed.

7 O nearest to the front of the range, shutting oh by this means the-passage of gas from the fire pots on either slde to the aperture 71 through the space between the strips 70 and enables these gases to be turned down 70 through passages 6t and 68, as hereinafter described, to heat the intermediate oven 52.

ture formed therefor in the plate 3. It is supported in any suitable manner. The water back 78 is provided with the usual connecting pipes 79 and 80 joining it to the water boiler 81. Between the hot water back andthe hot water boiler I place valves 82 and 83 in thepipes 79 and 80, by meansof which valves the water can be cut off from pairs or renewal of the water back 78, thus avoiding drainage of the hot water boiler. The upper portions of the spaces or passages 67 and 68 are provided with removable plates 8a and 85 which can be removed when the damper 7 O'is put in place and which can be closed when the damper 70 is open. Some advantage would ensue from the opening of all of these at the same time but they are preferably arranged to hat e the damper 70 and the plates 84 and 85 used in the manner as stated, the damper being open when the plates are in place and closed when the The operation is as follows:--The hot air from the fire pots, when the plates 84 and 85 are in place, has access to the space above the intermediate oven and above the plates 84: and 85 and can fiow around the ends of the strips 7 O nearest to the front of the range and through the space between these strips into and through the passage 71 when the damper 70 is open. This heats the top of the range and of course slightly heats the intermediate oven 52, heating the oven 16 115 also in its passage to the smoke pipe. The passages 74; and 75 carry but little of the gas or the hot air from the tire pots, as their path to the aperture 71 is more tortuous than the path just described. The gases from 120 passages 74 and 75 under these conditions i must pass through the spaces 67 and 68 through the apertures 66 and out the apertures 61 into space 58 by which communication is had with the opening 71. Very little 5 of the hot air passes in this way, in eonsequence, the most of it passing by the shorter path across the top of the intermediate oven 52. v

hen the plates 84 and 85 are removed 1 he-d mper 7. s e atm gases and. e ai former y flow ng aerossthiough l1e openings 76 and 77.. can not reach uthe'aperwr t ro gh eipre i uspa h, b t u 30W lo n thr ughv h spac and. 68 through theapertures66 and back through the apertures 61 into the space or, passage 58 following in this manner the same path as whatever gases previously flowed through the passages 7a and 75, but withthiS condition that no other path is then opened for hot air and gas from either of thefire pots than the one just named. The result of this is that the hot air and gas from both of the fire pots flows out through apertures 76 and 77 and passages 74 and 75 uniting in the spaces 67 and 68 and thus flow around and under the intermediate oven 52 heating it correspondingly. The action just named could take place of course whether or not the plates 53 and were in place, but most advantageously with these so placed.

The broiling grate is intended to be used primarily with the plates 84 and 85 and finds its best use under these conditions. The plates 53 and 65 are then removed. Access is had to the top of the broiling grate through the door 51 and the opening otherwise covered by plate 53. The hot air and gases from the broiling grate find their es.- cape through the space or passage 59, apertures 61 and space or passage 58. I have shown supports at the top of the passage 58 i and a plate providing removable means for cutting off this passage when desired, confining the flow of gas to that which passes between the strips 70. In any event the ultimate passage of the hot air and gases through the aperture 71 insures that they shall pass through the passages 17 and 18 on their way to the chimney and shall heat the oven 16.
